title: [Epilepsies during the first year of life].
abstract: OBJECTIVE
  An important number of epileptic patients who began with epileptic seizures during the first year of life have not just been well classified. The objective is to identify the different types of epilepsies and epileptic seizures which begin during the first year of life, according to the last classification of epilepsy and epileptic syndromes of 1989.
  
  
  METHODS
  We have studied 471 patients who consulted to our service in the last 5 years, with epileptic seizures during the first year of life. We excluded neonatal seizures and febrile convulsions.
  
  
  RESULTS
  1. Partial epilepsy: a) idiopathic: 12 (2.5%); b) symptomatic: 130 (28%); c) cryptogenic: 25 (5%). 2. Generalized epilepsy: a) idiopathic: benign myoclonic epilepsy in infancy, 6 (1%); b) cryptogenic-symptomatic: symptomatic West syndrome, 155 (33%); cryptogenic West syndrome, 65 (14%); cryptogenic myoclonic epilepsy, 6 (1%); early infantile epileptic encephalopathy, 8 (1.6%); early myoclonic encephalopathy, 4 (0.8%); other symptomatic generalized epilepsies without specific aetiology, 14 (3%). 3. Epilepsies and syndromes undetermined as to whether they are focal or generalized: a) severe myoclonic epilepsy in infancy, 15 (3%); symptomatic epilepsy with multifocal and independent spikes, 3 (0.6%); other undetermined epilepsies not defined above, 3 (0.6%). 4. Special syndromes: occasional convulsions, 15 (3%).
  
  
  CONCLUSIONS
  West syndrome is the commonest type of epilepsy during the first year of life, particularly symptomatic West syndrome. Symptomatic partial epilepsies are in the second place in frequency. We identified 12 patients with idiopathic partial epilepsy, who full-filled clinical and EEG characteristics of a recently described epilepsy: benign infantile familial convulsions. The study showed the predominance of symptomatic epilepsy, generalized (represented by West syndrome) and partials. Finally 6% of the patients have a generalized epilepsy, cryptogenic or symptomatic, not defined in the classification.
